SPECIAL TRAITS/TRIVIA:
--Doesn't suffer ill effects from any poison-style attacks (White Pikmin, Bellossom, et cet).
--Mike Myers refused to record new dialogue for the game, so they had to used old voice clips from 1998.
--All that glitters is, in fact, not gold.

It's April in part of the word already, so I figured I'd get this up now instead of being super late.
Looks like Sakurai changed his mind about "video-game-original characters only" after all.

I was really excited for the addition of such a legendary character but they might have gone too far. Good frame data, super armor on his side-smash, ridiculously good grabs and easy KO potential. The meta game is basically Shrek vs Robo-Marth now and it's already kind of stale.

I don't think Sakurai ever said that bit about "video-game-original characters only" in SSB. I've never seen a source and have actually seen evidence to the contrary, considering that he'd have put James Bond in if it hadn't been for legal hurdles.
